To convert 8-bit H.265 (HEVC) video to 8-bit H.264 without quality loss, you can follow these steps using FFmpeg, a powerful open-source multimedia processing tool.
Prerequisites
Before proceeding, ensure you have FFmpeg installed on your system. You can download it from the FFmpeg website.
Steps
-
Open a terminal or command prompt and navigate to the directory containing your 8-bit H.265 video file.
-
Run the following command to convert the video:
ffmpeg -i input.hevc -c:v libx264 -crf 18 -preset slow output.mp4
Replace input.hevc with the name of your 8-bit H.265 video file, and output.mp4 with the desired name for the output 8-bit H.264 video file.
Here's a breakdown of the command:
-i input.hevcspecifies the input file.-c:v libx264sets the video codec to H.264.-crf 18sets the Constant Rate Factor (CRF) to 18, which aims for a good balance between file size and quality.-preset slowsets the encoding preset to slow, which may take longer but can result in better quality.output.mp4specifies the output file.
